The idea of System X was conceived in March 2003 and designed in July of that year. By October 2003, it had achieved a sustained performance of 10.28 Teraflops (a trillion bytes of information), making it the third fastest supercomputer in the world today. Based on an Apple G5 platform, it uses a high performance communications system called Infiniband and is liquid cooled.
